Guitar Tuner: Chromatic

Tune guitar, bass and ukulele using your phone's microphone. Play one string at a time and follow the meter to see whether the note is flat, in tune or sharp. The tuner identifies the note you play and displays its frequency in Hz and pitch difference in cents, helping you follow each adjustment. FREE TRIAL, ADS AND PREMIUM Try the tuner for 30 minutes of use: an initial 20 minutes and another 10 minutes when you choose to continue the trial. Time is counted while you use the tuner with its microphone active. After the trial, you can watch a rewarded ad, when available, to unlock access for the current session. This access is temporary. Premium provides unlimited access through a one-time purchase, with no recurring subscription.
